The "memory card cannot be accessed" error would prevent you from taking photos or viewing files. As the full error message implies, [1] try to reinsert the card a couple of times, [2] change the card with a new one, or [3] format the SD card in the camera. Those manners are meant to make the card function well.

Before taking action to troubleshoot with suggestions, you must find a digital camera recovery solution first. Data recovery is prior to SD card repair, as long as you cannot afford to lose the media files in the malfunctioning storage card.

Quick Tip: If it's a brand new memory card that you use for the first time, make sure that you format the SD card to FAT file system, which digital cameras can recognize properly.

How to Recover Data from Inaccessible SD Card

Since formatting an SD card would wipe data out, do not rush to format the card if tons of pictures and video clips are there. Use EaseUS Data Recovery Wizard to recover files from an inaccessible SD card, and then remove the error with your camera or PC.

What if you've formatted the card before coming to this solution? Don't bother, EaseUS hard drive recovery software is still able to recover formatted SD card data. Try to protect your lost videos and photos from overwriting by taking new photos. This act would help keep the lost data intact and safe for recovery.

Step 1. Download EaseUS Data Recovery Wizard - the dependable SD card recovery software for Windows on your PC. Connect the SD card to your computer with either a card reader or by attaching the device that contains it. Launch the software so you can see the SD card from the disk list presented on the interface. Select the SD card and click Scan.

Step 2. The scan process should be running. A quick scan is able to quickly find the files that were recently deleted or items emptied from the recycle bin, and the later deep scan is useful for files that are harder to find, which might lose file names. During the course of scanning the SD card, you can start checking the results from the leftside tree-view pane, or simply use the Filter function to show up only the pictures, doucments, videos, emails and so on.

When you're asked to choose a location to save the recovered files, do not use the SD card but another drive, to avoid data overwriting.
